The Shocking Truth of Lightning Rods

The purpose of this experiment is to find the most conductive material after electricity passes air to be able to know which metals are best for lightning rods. The experiment consisted of turning a drum which touched fur and an aluminum can which had been cut to slide on the side of the drum. This caused static electricity to go into the aluminum can slicing, which was later passed into a copper rod that the aluminum can was tied upon. After it has reached this point it was again transferred to a Leyden-Jar. (Capacitator) After a reasonable amount of charge had been obtained, the Leyden-Jar was discharged. The length and strength of the bolt was measured when the discharge had occurred.rn My results have proven that brass is the most effective item for grounding electricity that has passed through the air. Of all the metals that were tested, the brass was sometimes by far the superior conductor of electricity. Brass managed to achieve bolts the size of 1.5 centimeters by 70 rotations. The Rest followed in this order: Aluminum, Copper, Steel and Stainless-Steel.rn This experiment had led to numerous other possible investigations. Experiments such as measuring how much electrical current and voltage it takes for a type of metal to be damaged or finding the most effective place to put a lightning rod to protect housing. Since the rods used in this experiment were extremely thin and small, it had led to the wondering of: What size is the most effective for protecting housing from lightning?
